The "Received" headers of your mails show the following arrival times:

                               first mail                   second mail
ladisch.de                     10 Sep 2003 20:23:30 -0000   10 Sep 2003 20:47:18 -0000
sc8-sf-list2.sourceforge.net   10 Sep 2003 12:56:20 -0700   10 Sep 2003 13:28:43 -0700
sc8-sf-list1.sourceforge.net   10 Sep 2003 09:16:28 -0700   10 Sep 2003 13:13:40 -0700
sc8-sf-mx1.sourceforge.net     10 Sep 2003 09:16:27 -0700   10 Sep 2003 13:13:39 -0700
vivaldi.controlnet.com         10 Sep 2003 09:48:12 -0700   10 Sep 2003 13:45:27 -0700

This translates to the following mail processing durations:

sc8-sf-list2.sourceforge.net   0:27:10   0:18:35
sc8-sf-list1.sourceforge.net   3:39:52   0:15:03
sc8-sf-mx1.sourceforge.net     0:00:01   0:00:01
vivaldi.controlnet.com        -0:41:45  -0:31:48

If we assume that all clocks are set correctly, we can conclude:

1) SourceForge's list servers are overloaded at times.

2) Your ISP (controlnet.com) has a time machine.  :-)

When an interrupt for MIDI input occurs, the hdsp driver disables all
further MIDI interrupts until the current input data has been read. I
don't know why it does this, but you may try to remove/disable lines
3181, 3182, 3188, and 3189 in hdsp.c.
